ROTARY-CYLINDER WASHING-MACHINE.

Specification of Letters Patent.

Application led December 10, 1907. Serial No. 405,948.

. To all whom it may concern."

f Be it known that I, CHRISTIAN residing lington and State of New Jersey, have 1nvented a new and Improved Rotary-Cylinder "Washing-Machine, of which the following is a specification.

i' y mventlon, which relates to laundry ma- JENSEN,

an improved rotary washing cylinder of that type used within a water holding casing, and it primaril has for itsv object to provide a machine o the character stated, of a simple and compact construction, which is easily mani ulated, ca able of eectively washing the c othes un er a minimum expense of power and time. v

With the above and other objects in view, ny invention comprehends with a stationary c tsing or tank, of a two-chambered cylinder, 1iaving similar, but alternately arranged means for causing the water within the casing to first flow into one section or chamber of the cylinder when it is revolved in one direction and then iiow therefrom and through the other section or chamber when the cylinder is revolved in the reverse direction, lthe actions in the two cylinder sections taking placereversely and alternately.

My invention, in its more complete nature, embodies a special construction of the two chambers or sections that constitute the cylinders, and comprising circumferentially disposed and longitudinal y extended blades whereby lto direct the water into one section for thoroughly rinsing and agitating the clothes in the water at the incoming side of the said section and providing for' pounding and washing the clothing in the other section at the bottom of the said section during the outflow of the water from the said other section, as the cylinder is revolved.

In its more subordinate features, my invention consists in certain details of construction and novel arrangement of parts,v

all of which will be hereinafter fully de` scribed, s ecifically pointed out in the appended c-aims and illustrated in the accompanying drawings, in which:-

Flgure 1, is a perspective view of the complete machine, asset up for use, the outer casing being broken away to show the revolving cylinder, one of the hinged doors of one section of the cylinder being opened. Fig hgs. 3 and 4 are cross sections thereof on the at Palmyra, in the countyof Buris arranged substantial lines 3--3 and 4-4 respectively on Fig. 2, land Fig. 5, is a diagrammatic cross section of the two compartments or c linder sections illustrating the direction o How of the water into one section as it flows out the other and the ap roximate positions of the clothes contained) in the said cylinder sections.

My invention, in its practical application, y as shown 1n Fig. 1, in which 1 designates'the outer casing or water tank into which the water is fed and from which it is exhausted in the usual manner, said casing having the usual end bearings for the stub shafts 2 (only one being shown) mounted on the opposite ends ofthe cylinder 3, which is driven by suitable drive gearing 4, that' receives motion from a drive haft- 5 as will be clearly understood from lt should be stated that in the practical arrangement of the drive mechanism, the drive shaft is driven reversely preferably two or three revolutions in one direction and then likewise in the opposite direction,te imlpart the desired reverse motions to the cy inder 3 for reasons presently explained;

., The cylinder 3, the construction of which is the essential feature of my invention, comrises two end heads .304-a and a centrally isposed head 31, the several heads being solid, preferably formed of a number of boards incased by a strong metal strap band 32, three heads being arranged as shown, whereby to provide two like chambers or sections designated by X-Y, each ofwhich` is of like size and has its several parts con# structed alike, excepting that the several scoops or blades of the two sections are reversely projected for reasons presently ex-` plained.

Since the detailed construction of the two sections or chambers are alike -a description of one sectlon will suffice for both.

At the opposite ends of section' X and made fast to the opposing heads -30 and 31 are a series of spacing blocks 33-33 concentricallyl dis osed, between the adjacent ends of which t the opposite ends of series of longitudinal ribs 34 the outerfaces 34, of

which are dis osed inside of the' eripheral bands on the eads whereby annu ar spaces 35 are formed and the said faces 34. form the bearings for the closure screen or wire netting 36'.

. A. diametrically opposite pair of the ribs 34 are extended inwardly to form lifting iianges 34b for lifting the clothes on the waterincoming side of the cylinder, as clearly shown in the diagrammatic view Fig. 5, by reference to which, the coaction of the two sections of the cylinder is shown, and by reference to which the relative positions of a series of scoop like blades 37, is shown. The blades 37 consist of thin flat boards, one of which is secured to each of the ribs 34 with their rear edges flush with the corresponding edge of the ribs 34 andwith their front ends extended beyond the ribs whereby to form restricted openings z, between the several ribs 3 4.

The front ends of the blades 36 are cut on a bevel that extends from the outer circumferential edge inwardly to the ribs 34, such shaping of the members 36 forming scoo ends 36, which, when the cylinder is trave ing in the direction of the arrow a on the one section `X, causes the said ends to act as scoops that lift the water and direct it and` cause it to flow u on the one side of the casing as indicated by lthe arrows at the left of Fig. 5, and thereby also causing the water to fa back into the section X, creating, as it were, a circulation of the water transversely through the said section X and by reason thereof, since a flow of the water is directed as stated, and shown, the clothes agitated and rinsed are also caused to take that direction of movement, such movement bein materially aided by the inwardly projectec rib members 34h.

It will be noticed that the scoop ends of the blades 36 are disposed inside of the circumference of the heads, this being done to provide for a positive inflow of the water scooped up through the section X. N ow, since the scoop blades in section Y are reversely disposed, it follows that since the flat or rear edges of the blades 36 engage the water, there will be little or no elevation of the water on the u -going side of the section Y, and hence litt e or no lifting action of the clothing by the rib portion 34h, the weight and outward flow of the water serving to subject the clothing in the bottom of the section Y, to a thorough pounding and washing as the clothes in the section X are being rinsed and agitated, and subjected to the beating of the water.

By providing a cylinder with two sections arran ed to act on the clothes in the manner state', ,fit is manifest that revolving the cylinder'first in one direction and" then in the other direction effects,v YIirst, a thorough pounding and washing of the clothes and then rinsing and agitating, the washing occurring in one section as the rinsing goes on in the other, thus cleansing the clothes quickly and under a minimum power and time. Each of Ithe c linder sections has a hinged section 38, w ich can be lifted up through a corresponding opening in the top of the main casing or tank, which openings during the operaton of the cylinder are closed by the sliding closure members 5, see Fig. 1.

The cylinder doors are also provided with screenedo eninUs 38, Fig. 1 and they have straps 40 vringed at 41 to the butts 42 and formed with housings 43 in which are held lock members 44 adapted to be slip ed into engagement with sockets 45 in the heads of the cylinder as will be readily understood by reference to Fig. 1, they being automatically held to their closed or locked position by any suitable means, such as springs held in the housings 43 and as indicated in dotted lines on Fig.`2.

In practice, the cylinder is revolved a number of times in onedirection and then likewise in the opposite direction and during these operations the water contained in the main casing or tank is forced through one cylinder section or compartment as it is partially emptied through the other section and then likewise forced through the said other section and emptied from the first stated section when the cylinder is reversed in its direction of movement, such reverse operations serving to positively cleanse the clothes contained in the cylinder, which it should be stated, are entered and lifted out of the cylinders through the openings in the top of the main casing.

thus described my invention,'

Havmg what I claim and desire to secure by Letters Patent, is.'---
